Note that you may find it useful to set the following environment
variables for your compilers prior to configuring/building:

setenv CC gcc
setenv CPPFLAGS '-DNDEBUG -Df2cFortran'
setenv CFLAGS '-O -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC'
setenv FC ifort
setenv F77 ifort
setenv FFLAGS -O

Could you send the version of each compiler you're using?

As well, is it possible to use either the Intel C compiler with
ifort, or alternatively, the GNU Fortran compiler with gcc?

Please be sure to edit the file $NCARG_SRC/config/LINUX to include
the proper set of libraries for mixing compilers. In this case, I
suggest starting with:

#define CCompiler gcc
#define FCompiler ifort
#define CtoFLibraries -lg2c -lgcc -lm -lifcore

and seeing how this goes. It may be necessary to iterate on these a
bit until you find the proper combination. I don't have a way to
test this locally.

Please also have a look at the ifort man page, specifically options
concerning the appending (or not) of underscores to external user-
defined names. The options in question are '-nus' (no underscores)
and '-us' (underscores) -- this may come into play when working with
the STSWM.

In looking at the output of the NCAR Graphics build, it shows that
libncarg_c.a is not being built. The 'make depend' portion of the
configure/build shows some errors I've not ever seen:

defined _FORTIFY_SOURCE && _FORTIFY_SOURCE > 0 && defined
__OPTIMIZE__ && __OPTIMIZE__ > 0 && (__GNUC_PREREQ (4,
1) || (defined __GNUC_RH_RELEASE__ && __GNUC_PREREQ (4,
0)) || (defined __GNUC_RH_RELEASE__ && __GNUC_PREREQ (3,
4) && __GNUC_MINOR__ == 4 &&
(__GNUC_PATCHLEVEL__ > 2 || (__GNUC_PATCHLEVEL__ ==
2 && __GNUC_RH_RELEASE__ >= 8))))
                                                                         
                                                                       ^
--- expecting )

Do you know where these might be coming from? Regardless, they are
preventing the proper configuration and dependency building for
libncarg_c, which then prevents it from building.
